1. A method for retracting a medial collateral ligament with a retractor comprising an arcuate projection having a convex retractor surface, a cutting shield surface, a guide projection extending from the cutting shield surface, and an aperture formed through the guide projection, the method comprising:
inserting the retractor into an incision at a surgical site proximal a knee joint;
maneuvering the retractor relative to the knee joint to locate the convex retractor surface on a lateral side of the medial collateral ligament and the cutting shield surface adjacent a tibial plateau of a tibia of the knee joint; and
placing the guide projection on a femur-facing surface of the tibial plateau,
wherein the aperture formed through the guide projection is shaped to expose at least a portion of the tibial plateau therethrough to guide a position of the retractor relative to the tibial plateau.
